CARBID-LDER REGISTER.

Application filed March 29,

To all whom t may concern:

Be it known that we, PAUL E. VEBB and FRANK A. VVnn, citizens of theUnited States, and residents of Protection, in the county of Comancheand State of Kansas, have invented a new and Improved Carbid- HolderRegister, of which the following is a full, clear, and exactdescription.

This invention relates to artificial gas lighting apparatus and hasparticular reference to acetylene gas generators.

Among the objects of the invention is to provide a self containedgenerating device including a carbid holder having means for dispensingor delivering measured quantities of the carbid from time to time intothe body of water at the bottom of the machine and provide means wherebythe operator may readily'observeat any time on the outside of themachine the amount of carbid retained inthe holder.

1With the foregoing and other objects in view the invention consists inthe arrangement and combination of parts hereinafter described andclaimed, and while the invention is not restricted to the exact detailsof construction disclosed or suggested herein, still for the purpose ofillustrating a practical embodiment thereof reference is had to Vtheaccompanying drawings, in which like reference characters designate thesame parts in the several views, and in which*- Figure 1 is a verticalsectional view of our improvement showing the carbid holder filled andthe parts in position corresponding to such condition; and

Fig. 2 is a horizontal sectional view of the same on the line 2 2.

Referring now more particularly to the drawings we show a generatingapparatus comprising a receptacle 10 for the body of' water 11 andhaving secured to the top 12 thereof an upwardly projecting dome for agasometer 13. These parts are shown as of cylindrical form, but as tothe design we do not wish to be unnecessarily restricted. 1We wouldstate also that with respect to details of the generator, such as themeans for controlling or delivering the gas and which have no immediatebearing upon the irnprovement described in detail, it will be understoodthat any suitable design or construction of machine may be resorted to.

Within the dome 13 is arranged a guide Speccaton of Letters Patent.

shown in the form of a hollow cylinder 11. The upper edge ofthiscylinder is fitted with a ring 15 and the lower end constitutes anoutwardly projecting foot or flange 16 through which it is secured tothe cover 12 of the base. The cover just referred to is open at 12 inits` center beneath the guide.

17 indicates an upright standard or lbraclfet secured as by bolts orrivets 18 upon the inner surface of the guide cylinder 14 adjacent tothe lower end of the same. This bracket includes a guide lug 19 having avertical eye at its upper end and at its lower end is provided with apair of ears 2O having horizontally alined holes.

21 indicates a supporting bar fitted slidably in the guide 19 andcarrying at its upper end a horizontal annular seat or ring 22 that isconcentric with the Guide cylinder. Beneath the supporting ring 22 is alever 23 having an open ring shaped body substantially directly belowthe ring 22. One end of the lever 23 is pivoted at 24 between the ears20, this constituting a xed pivot. i short distance inwardly from thefixed pivot is another pivot 25 through which the supporting bar 21 isconnected to the lever through a hub or knuckle 26. The opposite end ofthe lever from the fixed pivot is provided with a head 27 to which acoil spring 23 is connected Vat one end while the other end of thespring is adjustably connected through threaded bolt 29 and nut 30 to abracket 31 iixed upon the inner wall of the guide cylinder opposite thestandard 17. This spring 28 tends to draw upwardly upon the free end ofthe lever 23 thereby tending to cause the elevation of the rod 21 andthe supporting ring 22.

32 indicates the carbid holder, the same constituting` a receptaclefitted loosely within the ring or rim 15 and having a central conicalpoint 32 at its lower end seated in the annular seat or ring 22. To thelower end of this holder is secured any suitable measuring deviceadapted to receive a predetermined quantity of carbid from the holderand deposit the same downwardly through the center of the annular bodyof the lever 23 into the water 11. The holder 32 and the weight ofmaterial carried there` by serves to extend the spring 28, the weightaforesaid acting through the rod 21, knuckle 26 and lever 23. lVith thespring 28 carefully made of reliable material it will be understood thatthe lineal vextension of the spring will be directly proportional to theweight of the contents of the carbid holder.

For the reliable observation of the condition of the carbid holder orthe amount of material therein at an time, we provide on the outside ofthe mac ine a scale 34 graduated preferably from 0 to 100 or anysuitable minor graduations. Coperating with this scale 34 is an index 35carried upon the upper end of the rod 36 extending along a vertical tube37 extending through the cover 12 outside of the dome 13. The rod 36extends downwardly into the water and is bent inwardly and thenceupwardly into substantial U-shape and has its inner end pivotallyconnected at 38 to the lever head 27. Because of this direct connectionbetween the rod and the lever the extent of movement of the leverincident to the depression thereof by the weight or the elevationthereof, due to the action of the spring 28 when the weight is relieved,will be indicated directly by the index 35 upon the scale 34. Asindicated the lever is supplied with 100 pounds' of carbid which fact isindicated directly at the scale. lVhile the carbid may be dispensed fromthe holder as required, the index will move up proportionally and willalways point directly to the figure representing the number of poundsremaining in the holder.

We claim:

1. In a device of the character set forth the combination with areceptacle for water and a hollow guide member projecting upwardlytherefrom, of a bracket secured upon the inner surface of the guidemember, a carbid holder fittedslidably in the upper end of the guidemember, supporting means for the carbid holder comprising an annularseat through which the lower end of the carbid holder projects and alsoincluding a vertical bar fitted slidably in said bracket, a leverpivotally connected at one end to said bracket and having pivotalconnection with the lower end of said bar, and means Genies of thispatent may be obtained for connected to the free end of .the lever tocontrolits movement under the influence of the weight of the carbidholder and indicate the amount of suoli weight at any time.

2. In a device of the character set forth the combination with areceptacle for water having a cover with an open center and a hollowguide member surrounding said opening and extending upwardly therefrom,of a carbid holder guided for vertical movement in the upper end of theguide member and having a conical lower end arranged over the center ofsaid opening, an annular supporting seat through which the conical endof the holder projects downwardly, a'

supporting bar rigidly secured to the annular seat, a vertical.supporting bracket in which said bar is guided, a lever having one endconnected to a fixed pivot to the lower end of said bracket, pivotalconnections between the lower end of the bar and the lever adjacent tothe fixed pivot, said lever including an annular body arranged below theannular seat and through the center of which the material from theholder is adapted to be delivered into the water, and means connected tothe free end of the lever for controlling the movement thereof aroundsaid fixed pivot according to the weight of material in the holder andto directly indicate to the observer the amount of such weight.

3. In a carbid holder register the combination with a carbid holder andvertically movable supportin means therefor, of a lever connected witsaid supporting means adjacent to one end, a spring connected to theopposite end of the lever and tending to elevate the same and theholder, a U-shaped rod pivotally connected to the same end off the leverat the spring and extending in a direction opposite from the spring, agraduated scale and an index carried by the opposite end `of the rod andcooperating with said scale to show directly the weight in said holder.
